It was narrated that Abu Hurairah said:“The Messenger of Allah (ﷺ) said: ‘Whoever performs ablution and performs ablution well, then comes to Friday (prayer) and sits near (the Imam), and keeps quiet and listens, he will be forgiven for what was between that and the previous Friday (of sins), and three days more. And whoever touches the pebbles then he has engaged in Laghw (idle talk or behaviour).”
